A software-defined radio (SDR) system is a radio communication system which uses software for the modulation and demodulation of radio signals. An SDR performs significant amounts of signal processing in a general purpose computer, or a reconfigurable piece of digital electronics. SDR can talk and listen to multiple channels at the same time, also it can be quickly and easily upgraded with enhanced features. In fact, the upgrade could be delivered over-the-air In the long run, SDR is expected to become the dominant technology in radio communications

According with NATO Capstone Concept for the Military Contribution to Countering Hybrid Threats and EU Joint Framework to Counter Hybrid Threats, approved a new Military Strategy that will help set out NATO’s military priorities and approach to current and future challenges, including cyber and hybrid threats, instability across the Middle East and North Africa, and a more assertive Russia.[1]Hybrid conflict is defined as a dynamic interaction between elements of hard power (consolidation of military forces, deployment of military forces and capabilities in conflict zones, financing of separatist movements, activities to destabilize and undermine the security of a state or regions) and soft power ( maintaining an economic or energy dependence, applying economic sanctions, conducting propaganda, disinformation and influence campaigns, conducting cyber attacks, etc.)[2]. Hybrid warfare encompasses a vast area of hostile actions in which military force is only a small part of a flexible strategy with long-term objectives, complemented by political, economic and informational methods.

Unmanned Aerial Vehicle (UAV) systems have automated pilots that can be configured to suit various mission requirements. In this study, we assess, develop, and evaluate a bidirectional Wi-Fi communication link for an automated piloting system, utilizing the Cube Orange architecture that is mounted on a fixed-wing twin-engine airplane UAV. This Wi-Fi link enables seamless data exchange between the UAV and the ground control station. Using this bidirectional communication link, the user gains access to telemetry data, providing real-time insights into the UAV's flight parameters. Additionally, the user can send commands to the UAV, ensuring dynamic mission control and adaptability, while, the Wi-Fi link facilitates the retrieval of live video data from the UAV's onboard camera, enabling display on the command station screen or recording for future analysis and utilization. This comprehensive Wi-Fi communication system enhances the overall functionality and efficiency of the UAV's automated piloting, enabling smooth and reliable operations for various mission scenarios.

Language is the distinctive feature separating humans from the rest of the animal world. Therefore, throughout history, inventions and technologies that changed the way we use language have been crucial turning points. These include the invention of writing, which allowed the communication across space and time, the printing press, which facilitated the rapid and widespread dissemination of knowledge, and the advent of the Internet and mobile phone technology, which resulted in an explosion of communications and faster diffusion of knowledge. The latest revolutionary innovation in the field of language processing is ChatGPT, a generative AI model launched by OpenAI in November 2022, which produced spectacular results in natural language processing (NLP). It appears to be one of the most significant milestones in this field and has the potential to produce major changes in numerous domains, particularly in education. Starting from the available literature and from several experiments with ChatGPT, this paper outlines the main methodological requirements for using this instrument as an aid for self-directed learners.

Charles de Gaulle, « Le Général», is one of the emblematic figures of our century, an undisputed hero whose impact on the French nation and people was revolutionary, transformational and inspirational. The article proposes a qualitative, correlational meta- analysis, which stimulates reflection on his noble personality, on his visionary spirit, on his qualities as an affable negotiator. His virtues shape his destiny as a leader who worked in the spirit of dialogue, negotiation for modernization and freedom. Because of his exceptionalism, Charles de Gaulle can be considered a multidimensional leader. Characterised by a total leadership, his figure encompasses transactional, transformational, charismatic, informal, spontaneous leadership. Arguing through a deepening of scientific theories and exemplification of all these frameworks provides an elaborate and carefully researched perspective of a unique figure in French history.

We increasingly identify in our lives the presence of devices equipped with recording cameras, as well as facial recognition to unlock devices. At the same time, we notice the increasing presence of technologies capable of identifying different objects, manoeuvres or actions, as well as detecting actions performed in error. This article highlights how these digital devices can be integrated to improve the quality of maintenance and to achieve effective risk management in this sensitive segment of military RaDaR technology and equipment. The data acquisition elements (CWB/AR) can produce records that can be uploaded to a secure government cloud, which can be accessed by teams of appropriately skilled and qualified technicians. An IA structure can be adequately trained to notice, highlight and alert in case of deviations from the maintenance protocol, thus achieving quality management of the monitored equipment.
